Abstract

An integrated circuit comprising at least one microprocessor, an external connection interface, a data bus, an external address bus, a battery or dry cell supported data RAM (SRAM), a ROM containing at least one program and public keys, where at least part of said program is a cryptographic algorithm operating with the public keys contained in said ROM and at least one additional circuit with predefined functionalities. One application of this printed circuit is in the production of security modules, for example, for data terminals.
